When the circuit is connected as shown in figure 1.2, the switches of the emulator are set as SW2
= 1 and SW3 = 1. For details, refer to section 3.8, Setting the DIP Switches, in the SuperH
TM
Family E10A-USB Emulator User’s Manual.

Notes:
1.
2.
Supply the operating voltages of the H-UDI of the MCU to the UVCC pin. Make the emulator's switch settings so that the
user power will be supplied (SW2 = 1 and SW3 = 1).
The _ASEBRKAK/_ASEBRK pin (I/O pin) is multiplexed with the FWE pin (input pin). For the pin processing when the
emulator is used and the user system is independently in operation, pins must be pulled up at 4.7 kΩ or more or pulled
down at 100 kΩ. For the pin processing when the emulator is not used, refer to the hardware manual of the related MCU.
